Has anyone needed to lubricate their brake cable? I mean the sleeved cable that runs from the front bumper to the brake pedal. If so, what did you use? Some kind of tool? And any particular lube? Mine seems kind of stiff after our Minnesota winter.
Usually they require no lubrication as the cable slides easily in the sheath. I have not had to lube mine in 10 years. It's possible that debris or road salt has gotten into the cable over the winter. It may require slipping it out of the sheath and cleaning it off. Anything you lube it with will create the possibility of attracting dirt or other debris.
Over the ~10 years we've used it, I've occasionally lubed our ReadyBrake cable and conduit by spraying dry silicone in each end using the small straw that came with the can. It still works as well today as it did when it was new.
